Vetting a Newmarket contractor
Three checks that filter 90% of problems: (1) live WSIB clearance certificate, (2) named directors matching corporate filings, (3) two Newmarket references from the last 12 months you can call — not read.
Red flags on quotes
Verbal-only pricing, deposits above 20%, cash-only discounts, and unwillingness to itemise materials by brand are the top four. Any one is a pass.
What a defensible quote looks like
Written scope with photos, itemised labour + materials, 30-day validity, WSIB and liability certificate attached, and named workmanship warranty (5 years is the current bar for ice dam prevention).
Common questions
Do you need a permit for ice dam prevention in Newmarket?
Cleaning and inspection are permit-exempt in Newmarket. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
When's the best time of year for ice dam prevention in Newmarket?
Late September through mid-November with Newmarket averaging 154cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
What if it rains or snows on the booking day?
Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
Do you service condos and heritage homes in Newmarket?
Yes. Condo boards in Newmarket typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
How long does ice dam prevention take in Newmarket?
3–5 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
What warranty do you offer on ice dam prevention in Newmarket?
Five-year written workmanship warranty on materials and labour, transferable to a new homeowner within that window. Manufacturer warranties on any installed products pass through separately.
Are you WETT and WSIB certified?
Yes — WETT SITE-Comprehensive #C-46082, CSIA #12408, and active WSIB #7248194. Certificates emailed on request before the job.
How much does ice dam prevention cost in Newmarket?
Most Newmarket jobs land between $352 and $564. Complex access or heritage masonry can reach $916. We quote fixed price after a free on-site scope.
